UNITED STATES PATENT OFFICE.

OLYMPIO F. GAMBATI, OF HOUSTON, TEXAS.

COMBINED HEATER AND FILTER.

To all whom it may concern:

Be it known that I, OLvnrIo F. GAMBATT, a citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented certain new and useful Improvements in a Combined Heater and Filter, of which the following is a specification.

My invention relates to new and useful improvements in a combined heater and filter.

The object of the invention is to provide a device of the character described which is specifically designed to be attached to a dentists chair, and through which the water may pass from the water supply pipe and be discharged perfectly filtered and either hot or cold as may be desired. The device may also be attached to the ordinary water supply pipe and may be used wherever hot or cold water may be required.

Vith the above and other objects in view my invention has particular relation to certain novel features of construction and operation an example of which is given in this specification and illustrated in the accompanying drawings wherein Figure 1 is a side elevation of my complete device. F 2 is a plan view thereof. Fig. 3 is a sectional side elevation thereof taken on the line (Z(L of Fig. 2. Fig. is a sectional elevation of the filter. Fig. 5 is a detail view in elevation of the valve. Fig. (3 is a bottom plan view of the valve casing. Fig. 7 is a side elevation of the valve casing. Fig. 8 is aplan view of the valve seat.

Referring now more Jarticularly to the drawings wherein like numerals of reference designate similar parts in each of the figures, the numeral 1 refers to the heater casing which is connected to a similar filter using 2 by means of the bridge 3. These asings are preferably cylindrical in shape and are of *ast metal and have suitable bottoms cast integral therewith and have top members designated respectively by the numerals 4., 5, which are detachable and cast integral with the bridge 3.

The casing 2, contains a suitable filter (3, which is somewhat smaller in diameter than its casing so as to provide a watier-chamber 7 therearound, and is secured in place by means of tube 8 which extends upwardly therethrough. The lower end of this tube is exteriorly threaded to receive the interiorly threaded nut 9 which is designed.

to rest closely against the casing bottom and the upper end thereof is exteriorly threaded and screws into the boss 10 projecting down wardly from the center of the top member 5, and thus secures the top on the filter casing. The tube 8 has a washer 11 fixed there on within the bottom of the casing and interposed between this 'asher and the filter is a rubber gasket 12 provided to make the joint between the washer and. filter water tight. The tube 8 passes up through the filter loosely so as to provide a water chamber 13 around said tube and interposed between the filter and the top member 5 is a rubber gasket- 11 which surrounds the tube and closes the chamber 13. The interior of this tube communicates with chamber 13 through perforations 11 through which the water passes to the interior of this tube, and the tube interior communicates with water passage ways 15, and 16, controlled respectively, by the valves 17 and 18, whose structure is presently to be described' The numeral 19 refers to the valve seat which is cast integral with the bridge memher 3 and is provided with a central opening 20. A valve 21 is disposed above the opening and is secured in position by means of the valve casing 22 which fits over the valve and seat and is screwed on the seat as shown in Fig. 1. The valve is normally held closed by means of a coil spring 23, which operates in resistance to the casing and valve.

The upper face of the valve seat is pro vided with an arcuate groove opposing which is an arcuate downwardly extending passageway 25 through which the ater from passage way 20 may pass from valve 17 into passage way 26 shown in dotted lines in Fig. 2, and thence into discharge pipe 27. The water from valve 18 passes through passage way 28 and thence into pipe 29 which discharges near the bottom of the heating chamber of easing 1. The valves 17, and 18 may be opened by means of their respective thumb levers 30, and 81, fulcrumed on the stand 32 and having engagement with the valve stems as shown in Figs. 1, 2, and 3.

The numeral 33 refers to a heating tube which extends upwardly through the heating chamber and whose upper end is reduced and has threaded engagement with the top 1 thereof. The lower end of this tube carries a circular flange 3+1 which seats against the chamber bottom and the tube is screwed into said bottom and forms a water tight joint therewith. This tube is designed to carry an electric heater of any desirable type, which is provided with the usual connecting wires 36. These wires have a suitable connection with a generator (not shown). A gas burner may be used in lieu of the heater if it is so desired, and an open passage way 37 is provided to permit the escape of the fumes in case this character of burner is used. A deflector 38 is secured within tube 33 with passageways 39 around its outer edge and is designed to deflect the heat toward the walls of the tubes and thus elevate the temperature thereof.

The numeral 4-0, refers to a tube which extends from the top 4, down into the water chamber and has its lower end closed. This tube is designed to receive a suitable thermometer designed to indicate the temperature of the water within the chamber. \Vater is introduced into the filter chamber through inlet pipe 41 and after being filtered enters tube 8, through the perforation 1st and passes thence to passage ways 15 and 16. In case cold water is desired valve 17 is opened and the water is permitted to enter passage way 26 and is'discharged therefrom through the discharge 2?. In case it is desired to heat the water, valve 18 is opened and the water passes through the passage way 28 and pipe 29 is discharged near the bottom of heating tube 33 and is heated thereby and passes thence through port -12 and passage way 26 to discharge 27.

A detachable hinged member 43 is provided which embraces the casing 1 of the heater as shown in Fig. 2, and is designed for the purpose of securing the device to the chair to which it is to be attached and the heater and filter casings are preferably of the same size in order that the hinged member may be secured to either as may be desired.
